RUDIMENT #19 OF 40 · DIDDLE RUDIMENTS
The paradiddle-diddle is two singles and two doubles: R L R R L L. It does not alternate, so the right hand always leads, which makes it fast and very smooth.
R L R R L L
Capital letters are main notes. Small letters are grace notes played just before the main note.
Split between hands and feet or moved around the toms, it is a favorite fill pattern in rock and fusion.
